"Replicating ChatGPT Memory Functionality for Task Management and Skill Tracking" matching MCP servers:

Enables AI assistants to keep and retrieve private context locally, with verifiable receipts and optional Solana anchoring for public proofs.

Provides a persistent memory layer for Stellar and Soroban projects, scanning repositories to create a knowledge graph of contracts, storage, and on-chain state. Exposes this memory to AI agents via MCP, enabling project overview, search, and context recovery.

Enables interaction with AElf blockchain nodes, allowing users to read chain status, execute contract transactions, and manage custom nodes through MCP, CLI, or SDK.

Enables AI agents to inspect the public NFH protocol corpus, verify census status, and prepare bounded Ethereum wallet intents for claims and non-custodial market actions while never signing or submitting transactions.

This MCP wraps Bitrefill public API to allow agents to search for products and shop using cryptocurrencies like Bitcoin, Ethereum, Solana, and many more.

Enables AI agents to construct SHA-256 Merkle trees and generate/verify inclusion proofs, validate JWT HMAC-SHA256 claims, run Schnorr zero-knowledge identification, and enforce constant-time secret comparison with nonce replay protection for tamper-evident state attestation. It runs as a zero-dependency, stdlib-only MCP stdio server for clients such as Claude Desktop, Cursor, and Windsurf.

Enables Solidity callgraph and control-flow analysis to detect reentrancy vulnerabilities in smart contracts, with MCP integration for automated security auditing and DeFi vulnerability triage.

Enables autonomous Web3 security monitoring by watching honeytoken decoy private keys in the mempool to detect intrusions and trigger tripwire alerts. It also supports smart contract auditing, callgraph verification, and DeFi vulnerability triage through MCP.

Enables AI agents to perform financial transactions such as direct payments, escrows, and bounty management using natural language with zero code integration. It provides a comprehensive suite of tools for fund streaming, subscriptions, and reputation tracking to facilitate secure agent-to-agent commerce.

Enables AI agents to prove knowledge of a private key through a three-pass commitment, challenge, and response exchange, paired with SHA-256 Merkle inclusion proofs, JWT HMAC-SHA256 claim validation, constant-time secret comparison, and sliding-window nonce replay protection. Runs as a zero-dependency JSON-RPC 2.0 stdio server compatible with Claude Desktop, Cursor, and Windsurf.

Enables monitoring honeytoken decoy private keys for mempool activity, detecting and alerting on potential intrusions.

Enables agents and audit systems to hash execution logs into tamper-proof Merkle trees, compute cryptographic inclusion proofs, and verify audit-trail integrity on demand. It runs as a zero-dependency Python MCP server (stdio JSON-RPC) or as an importable module, exposing anchoring, proof generation, and integrity verification over local agent activity records.

Enables auditing EIP-712 typed signature phishing permits and sanitizing allowances (Permit2/MetaMask) via MCP, with deterministic callgraph verification and DeFi vulnerability triage. It integrates with Claude Desktop, Cursor, and MCP clients for autonomous smart contract security analysis.

Enables automated EVM flash loan arbitrage risk assessment and MEV sandwich attack protection for Aave and Uniswap v3, offering deterministic slippage and vulnerability analysis through the Model Context Protocol.

Enables autonomous auditing and sanitization of EIP-712 typed signature phishing attempts and permit/allowance risks, including Permit2 and MetaMask scenarios, through deterministic callgraph and invariant analysis with vulnerability triage.

Provides autonomous EVM smart contract auditing and DeFi vulnerability triage, with a focus on flash loan arbitrage price impact and MEV sandwich protection for Aave and Uniswap v3. Enables deterministic callgraph verification and signature phishing defense via a native Model Context Protocol server.

MCP server for Chainlink Runtime Environment, enabling build, simulate, deploy, and manage CRE workflows from any MCP client.

Enables automated Solidity smart contract auditing by analyzing callgraphs and control flow to detect reentrancy vulnerabilities. Integrates with MCP-compatible clients to provide deterministic, zero-dependency security assessments.

Enables auditing cross-chain bridge token reserve invariants and monitoring outflow spikes for LayerZero and Wormhole bridges, helping detect reserve anomalies and potential vulnerabilities.

Enables automated auditing of cross-chain bridge token reserves and monitoring for anomalous outflows on LayerZero and Wormhole, integrating with MCP-compliant clients for deterministic Web3 security analysis.
